Enzyme X is a highly pigmented protein that imparts the characteristic color to certain blue-green algae. It also facilitates a reaction necessary to the survival of this species; we can follow the kinetics of this reaction by measuring the conversion of Substance X to Substance Y at various times during purification.
1. Given a pure preparation of these algae, and the required supplies and equipment, devise and outline an empirical procedure for purifying Enzyme X.
2. What is a good indication of purity in your preparation?
a)A 10.0 g sample of a mixture of methane (CH4) and ethane (C2H4) reacts with oxygen at 25C and 1 atm to produce carbon dioxide and water (liquid). If the reaction produces 520 kJ of heat, what is the mass percentage of methane in the mixture?
